I have VOIP through Axvoice. I have had this with two desk phones. I
contacted desk phone manufacturer, and they deny any issue. They say that the
VOIP provider would have a certain setting. I didn't follow through and don't
know what that is. But my issue persists. Success with Cell phone. Thinking of
going to MagicJack. Anyone know why I would get busy signal when called party
picks up?
